As part of her graduate studies, Susan Hoskins apprenticed and was subsequently hired by Dave Bell Associates, a Los Angeles area documentary film production company that produced many of the early America Undercover documentary series for Home Box Office, including Victims Fight Back, Sex and the American Teenager, and Missing Persons Four True Stories, which was picked up as a pilot by NBC.
That show grew into what would become the long-running network television series Unsolved Mysteries, where Susan was promoted to editor, and remained for the full twelve year run. During that time she worked as an editor and sound recordist on the ethnographic documentary Horses of Life and Death (1991), produced by Laura Scheerer Whitney and Janet Hoskins, and several other projects funded by science and education grants. More recently, Susan has worked as an editor on non-fiction programs and series for most of the broadcast television networks, including Discovery Networks, NBC, CBS, KCET, Lifetime, UPN, HGTV, PAX, and TLC.
In collaboration with her sister, anthropologist and filmmaker Janet Hoskins, Susan directed and edited the historical documentary The Left Eye of God (2008), which screened at the Vietnamese International Film Festival. She also edited the Addy award winning Red, White and Green, in collaboration with Sierra Club Productions and Backcountry Pictures, which screened at the Environmental Film Festival.
